Company email (February 2012):
"Here at Lange Estate, we don't usually use any animal products in the production of our wine (in fact, we will go years without it sometimes). However, we are also not opposed to using them, either, and will use them if needed. So, unfortunately, I cannot tell you with certainty if any of our wines are vegan-friendly. I asked our winemaker that exact question and he said he cannot give a definitive vegan-friendly stamp on any of our wines."
